CLIP-RIVET.

i Specification of Letters Patent.

To a/Z whom, t may concern.'

Be it known that I, HERBERT F. COBB, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Clip-Rivet for Fastening Sheet Metal andSimilar Material to Buildings or other Structures, of which I herebydeclare the following `to be a full, clear, and eXact description, duereference being had and intended to the drawings accompanying and madeva part of this specification.

My invention relates and belongs to the class of articles orcontrivancesthat are used in and as a part of the construction of roofs, walls,floors, &c., and more particularly when such constructions are to havesheet metal in one or more of its various forms applied to the flangesof I-beams, channels, angles, and like structural material as thesupporting medium for said metal.

Heretofore, so far as I am aware, in order to secure the sheets inplace-on roofs, for instance-it has been the necessary practice to rivetthem to a clip in the form of an elongated piece or part of a suitablecontour to extend downwardly and beneath the flange. This operationrequires the services of two men, one above the plates or sheets todrive the latter down over the rivet and thereafter flatten the same andthe other, usually known as the bucker-up, beneath the plate to hold adolly-bar under the rivet during the process. Besides the undesirablecost thus involved there are other incidents characterizing theoperation that work to the same end, all of which it is the Obj ect ofmy present invention to overcome or reduce in a marked degree. Toaccomplish this, I provide a form of clip with an adhering rivet soconstituted and related'that it may be made to clutch the flange of thepart to which the sheet is to be applied and in such position to presentthe rivet for the downward blow and in this manner enable thebucking-up7 to be done by the Hange rather than by a man.

In the drawings, Figure l is a side view in elevation of the clip. whenin engagement with a flange. (Shown in section.) Fig. 2 is a frontelevation of Fig. l, but with the rivet driven homel through the sheetmetal, as in-o dicated. Dotted linesfindicate the rivet before theoperation. Fig. 3 is a plan view of 1 Fig. 1 with the flange omitted;and Fig. 4 is l a plan view of several sheets joined to the frame of astructure by means of said clip, which latter is shown in dotted linesbeneath. The sheets are represented as overlapping each other at theleft of the drawing.

The clip proper is an irregular shaped piece of any malleable Jnaterial,composed of upper and `lower jaws J and J respectively, suitablyseparated one from the other to receive between the same and fit ontothe particular fianges in each case in connection with which the clip isto be used.

In the drawings, F represents the flange. A rivet or rivet-stock Rprojects upwardly from and integrally with the upper jaw J, which jaw isgiven such vertical dimension that when the clip is seated on the iiangethe point of the stock R will be in immediate proximity to the placewhere it is to enter the sheet or plate. S represents such sheet orplate, and s supporting-strips for the same, that are sometimes used. I

W vis a washer that may be usefully placed on the rivet R before it isdriven down. In order to provide a sufficient bearing for the clip toinsure its upright position when in place on the flange, the upper jaw Jis given a crimp or turn from or across the vertical plane of the lowerjaw J, as shown by T in Fig. 8.

Having thus described said invention, the manner of using the samerequires little eX- planation. The clip is simply hooked onto the flangeas the workman proceeds, his one hand doing this as the other draws overand steadies the sheet upon the projecting rivet R. In this relation thesheet and rivet are given a downward blow through an interL posed block,as usual. The rivet will of course perforate the sheet and appear on theupper surface of the same, when it may be iiattened down in thecustomary manner.

Although as a concrete embodiment of my conception I have shown anddescribed a clip where the edges of the metal are the contactingsurfaces for the jaws, the bearing or crimp T is a simple inturn acrosstheir planes, and the rivet R is integral, I do not intend to limit thesame to a clip of precisely these characteristics. It is`conceivablethat a clip could be made, for instance, where the jaws engage theflange upon the fiat surface of the metal rather than the edge, theinturn be varied, or the rivet be distinct from rather than TOO integralwith the clip proper Without a departure from the invention When broadlyconsidered. Any Jform that engages the ange between j aWs or likemembers ior the purpose and in such position presents the rivet at itstop in such relation to the upper of said members that the latter Willserve as the anvil or bucker-up for the riveting bloW must fall withinthe scope of the invention.

Having described said invention, What I Wish to secure by Letters Patentis l. A clip-rivet made up of an upper and lower jaw, and a rivetsurmounting the same substantially as shown and described.

2. A clip-rivet for fastening sheet metal, or other material, to flangesand like parts, made up of an upper and lower jaw, the upper jawcarrying an upright rivet, and being raised to a suitable height tobring the point of said rivet in near proximity to the level at zo Whichit is to penetrate said material, when said clip-rivet is in engagement'with a flange, substantially as shown and described.

A clip-rivet for Jfastening sheet metal, or other material to flangesand like parts, made 2 5 up of an upper and lower jaw, the upper jawcarrying an upright rivet and being raised to a suitable height to bringthe point of said rivet in near proximity to the level at Which it is topenetrate said material When said 3o clip-rivet is in engagement with aflange, and being bent, or otherwise shaped, at an anule with the planeof the lower jaw substantially as shown and described.
